So, I was thinking this is how Daisy's crystal smash final smash might look.
Daisy rises into the air and forms a crystal gauntlet, like in strikers. Then she shoots it at the ground, teal crystals rising out of the ground in the form of a daisy, best seen on stages like Halberd or Smashville or something like that. It's big, and covers the entire stage. It would come out quickly too, sending those that get hit flying. Before the crystals go away, Daisy would gracefully fall to the ground and do a pose that's something like this
or maybe this
Once she does the pose, flowers pop out from behind the crystals like confetti before everything disappears and she continues fighting.
It was an idea I had. Tell me what you think of it though. I hope I explained it well enough and you can understand what I mean. I've never been the best at describing things.
